Because that way, you see, AH players could take some time off and catch some rays while the war wages. I suggest something akin to the Titanic or Queen Mary. Make it nice, complete with a band, a pool, and some sweet-ass shuffleboard!
Oh, and if the cruise ship happens to come to close to the action, those who are still on active duty should be able to attack and sink it--sending all the vacationing players back to the hangar still smelling like lotion.
Ba-da-bing!
